The technician was helpful and competent.
Mary Jo Sheridan
Prompt and efficient service. New AC unit is womderful!
Hari Cadambi
Mike from Princeton Air visited to give us a quote for a replacement water heater, both standard and tankless. I appreciated how informative the visit was and that Mike took his time to explain every little detail. Thank you!
Elizabeth
Cruise did a terrific “tune up” on our air conditioner. He communicated well and was thoughtful and knowledgeable. Very pleased!
Eric Thorkildsen
Excellent experience with emergency repair of an indoor AC unit that was time sensitive as we had renters in the beach house. They were quick, efficient and professional and were experts at a specialized unit that can only fit into small knee wall spaces with difficult access. Fixed the problem in the timeframe between one renter left and another came. Seamless! We really appreciated their responsiveness beginning with their salesperson Jason.
Carolyn Williams
Martique was great! He’s a real expert— very professional and knowledgeable. And a pleasure to work with!

Bought a home recently 25 yrs old. Needed to understand quality and workings of HVAC equipment had a good thorough inspection which I felt good about and then signed-up for an maintenance agreement.
Eric Sheier
Everything went according to plan. Easy. Nice people. Decent pricing. 0 percent financing for 18 months for an AC unit was key!
